Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-19T16:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-05-19T16:53:00-CME-001 (version 1)
Source Location: N33W25
Note Keyword:
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Visible in the NW of STEREO A COR2 and SOHO LASCO C2/C3. The start of the CME is not visible in SOHO LASCO C2/C3 due to a data gaps from 2024-05-19T15:16Z-19:12Z. There is continuing outflow following the initial leading edge of this CME. The source is a northwest filament eruption centered around N33W25 starting at 2024-05-19T14:33Z. The filament liftoff is visible in SDO AIA 193/304. Opening field lines and post eruptive arcades are also visible in SDO AIA 171//193. The filament eruption is also visible from the point of view of STEREO A EUV 195/304.
